土壤真菌中具有引起稻瘟霉孢子形态异常活性的菌株筛选

Screening of Strains According to Activities Inducing Morphological Abnormalities of Pyricularia oryzae from Soil Fungi

利用稻瘟霉孢子形态异常或生长抑制活性的模型 ,对从土壤中分出的 732株真菌进行初步筛选 ,得到 2 4 5株活性菌株 ,再经多次反复筛选 ,得到既稳定又能抑制一些病原真菌生长的11株活性菌株 ,其中 131号菌株活性最好且具有抗病原真菌作用 ,亦具有良好的遗传稳定性。

strains of active fungi inducing morphological abnormalities of pyricularia oryzae P 2b ,have been screened from 732 strains of soil fungi They also can inhibit fungi growth The activity of strain number 131 among the 11 fungi is the highest Its inheritance also is steady
